How does Chapter 30 explain the relationship between Sai's formless (Nirguni) and with-form (Saguni) states?

Chapter 30 of the Sai Satcharitra explains the relationship between Sai's formless and with-form aspects in a way that centers on the devotee's devotion. The text states that initially, 'You reside as the formless (Nirguni).' However, it is 'through the qualities of devotees' devotion' that He is drawn from this abstract state into a tangible 'form with attributes (Saguni).' This suggests that Sai's manifestation in a physical form is a direct, compassionate response to the love and needs of his followers, making the formless accessible to them.
